Patient-matched apparatus for use in spine related surgical procedures and methods for using the same

A patient-specific guide for posterior cervical surgery, comprising:

• a medial body;
• a holding tab extending from the proximal end of the medial body
• a first and second cylindrical column oriented in a predetermined trajectory;
• at least a first projection on the distal end of the first cannula;
• at least a second projection on the distal end of the second cannula;
• a first leg extending from the distal end of the medial body;
• wherein the first and second distal extensions and the distal end of the first leg comprise distinct patient-specific surfaces configured to mate with anatomical features;
• wherein the first and second cylindrical column further comprise a first and second bore configured to receive a tool or instrument to create an aperture in the at least one patient-specific feature.
